Blowing themselves up was not a glitch, it was a feature. Probably because they knew the Regulators wouldn't be so merciful to them after Burnham killed Osyraa. The Viridian continuing to fire on a practically immobile ship trapped in its hold presented the very real risk that they would lose their shields and get boarded again. If they couldn't jump out, there was no way they would've survived.maybe try before blowing up everything - possibly yourself included?
